The last few years have seen a dramatic improvement in our understanding of the origin of Lyα absorption systems. Hydrodynamic numerical simulations of cold–dark–matter–dominated universes have shown that the many properties of the Lyα absorption systems can be explained by a photoionized, space–filling, intergalactic medium. Lyα lines offer promising probes of the photoionizing background, the amplitude of the mass fluctuations at high redshift and the evolution of the equation of state of the intergalactic medium.
